WYOMING — An autopsy has shown a Wyoming soldier who died Dec. 14 while on a 15-mile hike in the Arizona desert suffered a punctured lung that likely caused her death.

The final cause of Pfc. Moneeka Mayo Vander Geld's death remains pending, said Dennis Mayo, her father.

The 29-year-old will be laid to rest this weekend at an 11 a.m. Saturday memorial service at Banner of Christ Church in Byron Township. The family also will have a 10 a.m. to 3 p.m. Friday visitation at Matthysse-Kuiper-DeGraaf Funeral Home in Grandville.

Vander Geld suffered a rib injury about 10 days before the grueling hike, during which she was carrying a 30-pound pack on her shoulders. A U.S. Army investigation into the death is ongoing, Dennis Mayo said.

Vander Geld is survived by her husband, Delano Vander Geld, and children, Elece, 6, and Beeaja, 1. She also was the stepmother of Alexi, 11, and Cameron, 9. Vander Geld had eight years of reserve experience and joined active duty on July 30.
